BOTTLE CAP Filed Feb. 7, 1945 AV/f/VTOR PA /*5 614 new 6,

ATTOR/VA-Y Patented Jan. 15, 1946 UNITED STATES PATENT OFFICE' 5 Claims.

This application is a continuation, in part, my application. filed February 16, 1944, Ser. No. 522,629.

The invention relates to a bottle cap and it consists in the constructions, arrangements and com- 7 binations herein described and claimed.

It is a cardinal object of the invention to provide a ca'p construction which may be readily and quickly applied to a beverage bottle to efiect proper seating thereof, after removal of the conventional cap.

It is a more specific object of the invention to provide a compressed cap member interconnected with a ring member complemental to the neck of a bottle, the ring member including a cam lever for imparting a uniform compressive force to the body of the cap to effect a full and even seating of the cap within the mouth of the bottle, and for retaining the cap in such position against gas pressures which may be developed from liquids contained in the bottle.

Additional objects, advantages and features of invention will be apparent from the following description considered in conjunction with the accompanying drawing, wherein:

Figure 1 is a perspective view of the cap.

Figure 2 is a side elevation of the cap in use upon a bottle, a portion of the bottle and cap being broken away,

Figure 3 is a top plan view of the cap.

Figure 4 is a cross section on the line d-@ of Figure 2.

Figure 5 is an enlarged fragmentary cross section illustrating the connection of the bail members and the clamp.

Figure 6 is a fragmentary elevation of a bottle illustrating a modified form of the cap.

Figure 7 is a top plan view thereof.

tremities and receive a divided clamping ring therethrough. The legs I9 are of such length as to position the ring 20 slightly above the groove l I of the bottle, for a purpose as will appear.

The ring 20 is formed with. circumferentially spaced loops 20' positioned so as to receive respective eyelets l9 therewithin, and as may be,

seen in Figure 3, the loops 20' are outwardly disposed with respect to the bottle neck so as to accommodate the thickness of the material forming the eyelets. Byinterlocking the bail members and the clamping ring in this manner, the bail members are held against slippage and 1118111!- ing a straight downward pull upon the cap when the cap is seated.

The ing 20 has a hook member ii at respective ends arranged in opposed relation to one another and receive respective eyelets 22 of a cam lever 23. The operation of the cam lever 23 is well understood in the art, and a detailed explanation is not believed necessary, except to state that when the lever is moved downwardly so as to rest upon the neck of the bottle contraction of the ring 20 will have been effected, drawing the ring 25 snugly into the groove H of the bottle. As the There is illustrated a portion of a beverage bottle it of conventional form, in which a i i is formed inwardly of the mouth I2.

The cap I 3 is molded from rubber or other resilient material such as certain plastics. The cap is of a diameter greater than the mouth it of the bottle and includes an axial stopper M of slight depth. The underface i5 of the cap is planiform and circumscribes the stopper it. A pair of bail members it are embedded or otherwise secured in the material of the cap i3, and as may be seen in Figure 1, the bail members are substantially U-shaped, the bight portion l'l being of a width so as to present respective leg members !8 upon opposite sides of the neck of a bottle when the cap is engaged thereon. The leg members are each formed with an eyelet I9 at their exgroove ring 29 is contracted there will be a downward pull upon the legs it, thus drawing the stopper it into the mouth of the bottle and the underface it into firm engagement with the upper open end or mouth of the bottle, the face it being compressed so as to assume the contour of the mouth as shown in Figure 1. By having the bails ii in spaced parallel relation, an even pressure is de= veloped throughout the body of the cap, which may also be attained by arranging the bails in a crossed relation, as shown in Figure 7.

While I have shown and described preferred constructions, this is by way of illustration only, and I consider as my own all such modifications in construction as fairly fall within the scope oi the appended claims.-

I claim:

1. A bottle closure comprising a resilient cap, a pair of bail members fixed in the cap each having downwardly extended legs terminating in eyelets, a divided ring engaged through respective eyelets of the legs and having. respective looped ends and -cam means operatively engaged with the looped ends of the ring for contracting the latter around upon the legs of the ball members when said closure is engaged within the neck of a bottle.

disposed through the eyelets and having respective looped ends, said ring normally occupying a position slightly above the groove of the bottle, and cam means operatively connected with the looped ends of said divided ring for contracting and drawing the divided ring into said groove and eflecting a downward pull upon said legs.

5. The structure of claim 4 in which said divided ring is provided with circumierentially spaced loop portions adapted to interlock with respective eyelets of said leg members.
